Felicia Ann,
If you think that you may have this issue, you can request a fairly simple test called the 'Tilt Table' test from your doctor.
You may also want to get a referral from your regular doctor is all of your routine tests have come back clear. A neurologist may be able to shed some more light on your symptoms...have you been checked for migraines? Often you can present with the symptoms/auras, but not the pain. Some of your symptoms sound like they could be migraine related.
You are wise not to put your e-mail...thanks for asking about
this...it is not safe as this is a public forum. If you wish to get in contact with a member, check and see it their e-mail is in their profile. You do this by clicking on their screen name. (anywhere on the site)
If their e-mail is not in their profile, you can add yours and ask them to contact you...however if someone has invited you to contact them, then they should allow you to e-mail them first by having theirs available, in my opinion.
Take care, and keep at your doctor for answers!
S.C.
